'-Be it known that IVRicHAnDWii-ii Binz A nm,`afcitizen of the Uni-ted. States of America, residing at the city foi*V Montreal,

.Province of Quebec, Dominion off'Canada, have invented certain new and useful linprovements in Draft-Rigging for A`Railway- Cars; and I do hereby declare. that the following is a ffull, clear', andexact description of the saine. Y

My invention. relates particularly'to the connection lbetween the spring pocket or yoke and the shank ofthe draw-bar, and it hasor its object to render this connection more. durable and'reduce to a ininimuinthe breakageor distortion of the spring 'pocket f and breakage or loss of the connecting pin.

Careful-investigation has shown that failure of the connection is due to the spreadiig of the yoke-or pocket thust'hrowing a lien` ing strain on the pin causing it to break. These accidents are prevented by my invention vwhich consists of a rigid' collarY adapted to encircle the shank of the draw- -bar and having a pairv of integral lugs vadapt-ed to straddle the ends of the spring '.pocket, such lugs bein@lr constructed to ac- A ,cominodate the vends o? the connecting pin 8o one end of which is locked'in one of the lugs.

Eor full comprehension, however, of my invention reference must be had to the ac- 4eonipanying drawings forming a part of this 'specificationin which similar reference charactersindicate the same parts, and wherein:

The lugs 'are indicated at f and g and they are prefera'bly located' at the top and bottom respectively.'v The top lug has a chamber or.socket -k to receive the upper end-of the connecting pklm'and'tlie bottom hghas an opening if:

f through which'the pin is inserted, this .lug valso having a pairA of holes'p 7;. registering with a transverse hole in the pin fora' splitI cotterpin o. In order to piotect the'- cotter of suliiciently less width thanthe Y collar` to 'accommodate' the ends of the pin, the side portions of such lip being of greater depth than the middleportion to contain the holes p without unduly weakening the saine. This feature is clearly shown in Fig. 2. The top lug-has aboss containing the chamber. or socket k the top-of the boss having a hole r to permit the pin to be driven out when necessary. Collar d and lugs are braced by flanges lv located at the sde edges of the top and bottom .thereof and-extending around the lugs to forin `in one'casc the lip g, and

in the other case the front wall of the bossV f.' With my improved connection a headless connecting-pin-maybe used thus ermitting it to besinscrted from belowv an locked in place by the Cotter pin o'thereby obviating the necessity of cutting an opening inthe floor ofthe car to remove the pin as has been the practice heretofore. It also ob'yiates the necessityv of delay .in the event of a broken pin as thedamaged. pin may berexnoved .by-simply withdrawing the Cotter pin and a straddle the ends of'the yokeor spring pocket and 'a pin effecting connection 'be-- tweenv the draw-bar shank and'thespring' pocket or yoke, the said'lugs being constru'cted `and arranged to receive the e'ndso` the connecting pin., g
